Arduino RC Transmitter

Forum 2005-2010 (read only) General Exhibition

Hi Folks,

I have posted bits about this project on here before, but now version 1 is complete I figured it could be added to the exhibition.

I have built a seven channel RC transmitter by creating a new PPM board for my old 35mHz transmitter.


I haven't yet flown with it as I don't currently have a flight worthy aircraft, but I am working on it!

The firmware currently caters for:

  • Four sticks mapped to 4 output channels according to the 'mode' that the flyer uses.
  • Dual rates on elevator and ailerons activated by two of the switches
  • Exponential available (but I am not currently using it)
  • V-tail mixer for coupling elevator and rudder on vtail models
  • Differential ailerons
  • Delta mixing with differential ailerons.
  • Battery voltage sensing with visual level representation using two LED's (red and green)
  • Test mode that sweeps one output channel. Good for range testing on your own!
  • Ability to save the current settings to EEPROM and load them again (not in use yet, but will be soon)
  • Servo reversing
  • Servo center point and end point adjustment

The code can be downloaded here:

I have written a blog article on the whole thing is you want to know more

Very nice, congratulations!

What did you do with the source code file? When I extract it, all files are shown in green color in explorer (encrypted?) and I can't move or open the files.

Ok, got it to work with the zip file. Not sure what I did anymore, but I think files were read only and I had to unblock (?) encryption.

Ah.... looks like a permissions problem! I'll chmod the files to 777 and re-upload!
